Not catching the exception

When I try submit this, it keeps telling me that it is not catching the exception. What have I done wrong here so that it is not catching it?

Main.java
public class Main {
    public static void main(String[] args) {
        GoKart kart = new GoKart("yellow");
        if (kart.isBatteryEmpty()) {
          System.out.println("The battery is empty");
        }
        kart.drive(2);
      try {
        kart.drive(100);
        System.out.println("This will never happen.");
      } catch (IllegalArgumentException iae) {
         System.out.println("Not enough battery.");
      }
  }
}

Hi Lee Morgan,<p>

Here, you were not asked to add a new drive() method.</p><p>

Instead, you were asked to catch the exception that may be thrown when the existing drive() method is called.</p><p>

In order to pass the challenge, you may Either use a try-catch block with the existing drive() method OR will have to ensure that every call to the drive() method is enclosed by a try-catch block.</p><p>

So, either of the code below should work.</p>

public class Main {
    public static void main(String[] args) {
        GoKart kart = new GoKart("yellow");
        if (kart.isBatteryEmpty()) {
          System.out.println("The battery is empty");
        }
      try
      {
        kart.drive(2);
      }
      catch (IllegalArgumentException iae) {
         System.out.println(iae.getMessage());
      }
    }
}
public class Main {
    public static void main(String[] args) {
        GoKart kart = new GoKart("yellow");
        if (kart.isBatteryEmpty()) {
          System.out.println("The battery is empty");
        }
        try
      {
        kart.drive(2);
      }
      catch (IllegalArgumentException iae) {
         System.out.println(iae.getMessage());
      }
      try {
        kart.drive(100);
        System.out.println("This will never happen.");
      } catch (IllegalArgumentException iae) {
         System.out.println(iae.getMessage());
      }
    }
}

try {
        dispenser.load(400); 
      } catch (IllegalArgumentException iae) {
        System.out.println("Whoa there!");
        System.out.printf("The error was: %s%n", iae.getMessage());
      }

Above, is the code example to follow. Instead of dispenser.load(400), you are trying kart.drive(2)
